  • 이 연구는 개발가능성이 높은 지역이 규제지역으로 설정되어 있을 때 규제지역과 규제지역의 주변으로 규제저항이 발생할 것이라는 전제에서 출발한다. 그리고 이에 대한 분석은 GIS를 활용한 공간분석 방법으로 수행하였으며, 평창을 연구지역으로 하였다. 평창의 환경관련 규제현황을 조사하여 환경규제지도를 제작하고, 평창지역 전체의 상대적 개발 가능성 정도를 등급화 하였다. 그리고 이렇게 제작된 규제지도와 개발가능성등급도를 이용하여 상대적인 규제저항 정도를 측정하였다. 그 결과 평창의 환경관련 규제 비율은 남한강 유역권 전체의 규제 비율 보다 높게 나타났으며, 개발 가능성이 높은 지역과 환경 규제지역을 중첩하여 분석한 결과 읍면단위에서는 도암면과 진부면의 규제저항이 높을 것으로 예상되었다. 그리고 평창의 신규건물(1999년 $\sim$ 2005년) 입지와 환경규제와의 관계를 분석한 결과 개발가능성 등급이 높고 규제지역과 인접한 지역에 집중적으로 분포(신규건물의 약 66%가 규제지역으로부터 500m 이내 지역에 분포)하였다. 이러한 결과로 볼 때 지방정부와 주민에게 직접적인 이익을 제공하지 못하는 규제권역 설정 위주의 환경정책은 난 개발과 그에 따른 환경파괴라는 내재된 문제를 지니고 있음을 보여주는 것이다.

  • This paper presents a discrete-time version of voltage and current limited operation using an enhanced direct torque and flux control method for interior permanent magnet synchronous motor (IPMSM) drives. A command voltage vector for airgap torque and stator flux regulation can be uniquely determined by the finite-settling-step direct torque and flux control (FSS-DTFC) algorithm under physical constraints. The proposed command voltage vector trajectories can be developed to achieve the maximum inverter voltage utilization for the discrete-time current limit (DTCL)-based FSS-DTFC. The algorithm can produce adequate results over a number of the potential secondary upsets found in the steady-state current limit (SSCL)-based DTFC. The fast changes in the torque and stator flux linkage improve the dynamic responses significantly over a wide constant-power operating region. The control strategy was evaluated on a 900W IPMSM in both simulations and experiments.

  • This study explored the relationship between children's emotional competence, aggression and peer relationships. Participants were 164 third and 134 fourth grade children from five elementary schools in Seoul and Chenan. Emotional competence, aggression and peer relationships were assessed by means of a questionnaire, interview and observation. Results indicated that emotional understanding of self and others, sex, age, emotional expression and passive regulation strategies were significant variables in predicting children's aggression. Emotional understanding was the most predictable variable in relation to peer relationships. Emotional understanding, emotional regulation and emotional expression made independent contributions to aggression and peer relationships. Mediation analyses revealed that the significant connections between children's emotional competence and negative peer relationships were mostly mediated by aggression.

  • A spacecraft power system can be divided into two types : DET system(Direct Energy Transfer system) and PPT system(Peak Power Tracking system). In a DET system employing the regulated bus voltage control method, the battery charger and discharger are widely used for the bus voltage regulation. The battery charger has two different modes of operation. One is the bus voltage regulation mode and the other is the charge current regulation mode. The battery discharger is employed to provide the power when the spacecraft is in the earth's shadow or the sun is eclipsed. The operating mode, charging or discharging, is selected by a power control circuit. In this paper, small-signal dynamic characteristics of battery charging and discharging system are analyzed to facilitate design of control loop for optimum performance. Control loop designs in various operating modes are discussed. Anaylses are verified through experiments.

  • The purpose of this study is to test pollution-heaven hypothesis on the korean pollution-intensive industries, that is, textile and clothing, petrochemical and primary metal industry. The empirical study examines that foreign direct investment(FDI) of korean pollution-intensive industries regresses on couple of exogenous variables and the environmental regulation on FDI. As the environmental regulation is not directly observed, it uses $CO_2$ emissions as the pollutant. The results of the study show that the environmental regulation in a host country is an insignificant determinant of FDI for the korean polluting industries. That is, they do not support Leonard (1988), Xing and Kolstad (2000) that the hypothesis is a significant for heavily polluting industries.

  • Occupant injuries are always possible in a rollover accident, one of the major accidents in a bus. Thus the structure of body frame should have sufficient strength to protect passengers under accidental loads,. ECE(Economic Commission for Europe) regulation No.66 prescribes that residual space shall be preserved in the passenger compartment during and after the structure has been subjected to the prescribed rollover test. Rollover test on a bus section was completed according to the regulation. The coordinates of body section before and after rollover were measured, and it was checked that the structure still complied with the requirements of residual space. Direct measurement on a bus is difficult because of its large size. Thus photogrammetry by photographing and 3 dimensional digital modeling was introduced, and the coordinates of each point were measured through this method.

  • Objectives: This study was to develop a measurement scale that explains aggressive regulation behavior of middle school student, based on Ajzen's Theory of Planned Behavior (TPB) and verify its validity and reliability. Methods: The basic items were modified by selecting 41 items of middle school student aggressive behavior measurement scale. Through the content validity test, 63 first preliminary question items and 42 second preliminary question items were developed. The participants were 286 middle school students. The collected data were analyzed using content validity, correlation coefficient, exploratory factor analysis, confirmatory factor analysis, reliability and Cronbach α. Results: In this study, it was proved that the most important variable showing aggressive regulation behavior was aggressive regulation intention. This study was composed of 4 factors for direct measurement(attitude toward the behavior, subjective norm, perceived behavioral control, behavior intention) and 5 factors for indirect measurement(behavioral beliefs, outcome evaluation, normative beliefs, motivation to comply, control beliefs). The total variance was 65.4% and 67.6%, respectively, and the reliability was .90, .82. Finally, 42 questions were developed. Conclusion: We found the questionnaire used in this study was valid and reliable as a measure scale to explain the aggressive regulation behavior of middle school student based on TPB. Therefore, it is concluded that the aggressive regulation behavior scale could be a useful scale for the measurement of the aggressive regulation behavior of middle school student.

  • In current times, obesity is a major health problem closely associated with metabolic disease such as diabetes, dyslipidemia, and cardiovascular disease. The direct cause of obesity is known as an abnormal increase in fat cell size and the adipocyte pool. Hyperplasia, the increase in number of adipocytes, results from adipogenesis in which preadipocytes differentiate into mature adipocytes. Adipogenesis is regulated by local and systemic cues that alter transduction pathways and subsequent control of adipogenic transcription factors. Therefore, the regulation of adipogenesis is an important target for preventing obesity. Myonectin, a member of the CTRP family, is a type of myokine released by skeletal muscle cells. Although several studies have shown that myonectin is associated with lipid metabolism, the role of myonectin during adipogenesis is not known. Here, we demonstrate the role of myonectin during adipocyte differentiation of 3T3-L1 cells. We found that myonectin inhibits the adipogenesis of 3T3-L1 preadipocytes with a reduction in the expression of adipogenic transcription factors such as C/EBPα, β and PPARγ. Furthermore, we show that myonectin has an inhibitory effect on adipogenesis through the regulation of the p38 MAPK pathway and CHOP. These findings suggest that myonectin may be a novel therapeutic target for the prevention of obesity.

  • OTT와 VOD 서비스의 활성화로 시청행태는 급격하게 변화하고 있지만, 편성규제는 과거와 동일한 방식의 비율 규제에서 벗어나지 못하고 있다. 이에 본 논문은 현행 편성비율규제의 정책적 타당성을 검토하고 이를 바탕으로 개선방향을 제시하는 것을 목표로 한다. 이를 위하여 국내편성비율규제 도입 당시의 정책적 목표와 배경을 고찰하고 이를 현재의 방송시장 현황과 비교하여 살펴보았다. 그 결과, 본 연구는 현재 편성비율규제가 도입 당시의 비대칭규제라는 논리적 틀이 그대로 적용되기 어려운 시장 환경에 놓여 있음에도 불구하고, 비대칭규제를 기반으로 형성된 여러 이해관계자들의 상호관계 속에서 기존의 틀 속에서 미세한 비율의 조정만을 반복하는 경로의 존성의 전형적 모습을 보이고 있다고 지적하였다. 이를 바탕으로, 본 연구는 편성규제가 규제의 목적에 따라 공익적 목적에 의한 규제와 산업적 목적에 의한 규제로 구분하여, 시청자의 공익에 해당하는 직접적 규제로 한정되어 적용될 필요가 있으며, 규제와 진흥의 분리, 그리고 비대칭규제의 해소를 제안하였다.
